Think how much it would suck to wake up one morning only to find that your wheels had been stolen from your car! Not much fun hey?
So how to protect your wheels?
Most alarm systems do not protect against wheel theft. Whilst some alarms have a shock/vibration sensor, the reality is that these are generally found on cheap systems and are one of the biggest causes of false alarms, especially in windy Wellington where cars can get rocked about! Personally I’m not a fan of alarms that cry wolf so try to avoid these..
Tilt sensors don’t pick up vibrations, instead they look for a constant change in angle which makes them far more effective. When the alarm is armed the tilt sensor learns the angle in which the vehicle is parked. If it then sees a the car tilt more then about 1.5 degrees it will trigger the alarm system as shown in the video below:
Of course my alarm is also hooked up to a GPS pager which will then call my cell phone.
It’s not just the wheels that the tilt sensor protects against as any attempt to tow the car will also trigger the system.
A tilt sensor can be fitted to most alarms, but what I like most about fitting it with a Cobra alarm is having the option to disable it via the remote control so I can take the car on the ferry and still being able to arm the system. (Reminds me that I need to visit the Mainland again 😛 )

Obsessive Rating: Wheely good (Sorry!)
I’m aware of some other tilt sensors that have issues (and yes these are know NZ models so be warned!)
